A.  How long does the bullet take to travel through the barrel after it is fired?

    t = 0.127%2F180 seconds = calculate it on your own  // the barrel length divided by the average speed //



B.  What is the acceleration of the bullet while it is in the barrel?

    Acceleration  a = 360%2Ft m/s^2 = calculate it on your own.



C. What is the force (N) applied to produce this acceleration?

    The force is  F = m*a = 0.008*a "Newtons",  mass (in kilograms) multiplied by acceleration, which you will get from n.B).

Solved.
